Optical Variability of Blazars in the Tomo-e Gozen Northern Sky Transient Survey
TianFang Zhang, Mamoru Doi, Mitsuru Kokubo +14
We studied the optical variability of 241 BL Lacs and 83 flat-spectrum radio quasars (FSRQ) from the 4LAC catalog using data from the Tomo-e Gozen Northern Sky Transient Survey, wi…
